Abstract

PROBLEM TO BE SOLVED: To provide a most favorable lift selection method of a lift device furnished with at least two lift, groups. SOLUTION: This most favorable lift selection method of the lift device furnished with at least the two lift groups is related with a method that routes (W1;..., Wn) accompanied by changeovers (U1, U2, U3) to reach a destination floor (Z) from a departing floor (S) can be used, the routes are divided into various stretches (W1T1,..., W1Tn, WnT1,..., WnTn) and a lift of the one group of the lift groups (GR) is allotted to each of the stretches (W1T1,..., W1Tn, WnT1,..., WnTn). Under this method, it is possible to provide a means of settling a multi-route problem in destination call multi-group control especially accompanied by journeys with the changeovers concerned.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of selecting a most preferable lift for a lift device having at least two lift groups.

[0002]

From patent specification EP 0891291 B1 a multi-group control of several lift groups with destination call control and immediate assignment is known, in which the destination call input is, inter alia, to a specific lift group. The lifts assigned and assigned to any unregistered call registration device can be identified in a clear and simple manner.
It should be understood that the immediate assignment assigns the most preferred lift to passenger destination calls. As such, passengers do not need to know the division of the building into floor ranges that are served by individual lift groups only. Passengers are informed in the lift cage, at optimal time, by visual and audio instructions about the next connection to the destination floor. However, it does not provide an exact method of how conventional multi-group control selects the most preferred lift when the changeover between the departure floor and the destination floor is accompanied by a changeover. At the same time, it does not show how the multi-group control chooses the most preferred route when there are several routes to reach the destination floor.

[0003]

SUMMARY OF THE INVENTION The object of the invention is to propose a method of displaying the exact procedure for selecting the most favorable lift in the case of a journey which requires passengers to change trains of the kind described in the introduction. That is.

[0004]

This object is achieved by the features of claim 1.

It will be appreciated that an advantage of the present invention is to select the best lift cage in terms of cost, from the departure floor to the destination floor. Therefore, passengers can reach the destination floor as quickly as possible without wasting time.

Advantageous developments and improvements of the method of claim 1 are possible with the method of the dependent claims.

In one embodiment, each of the lift groups has an associated group control. This has the advantage that each lift group can be controlled automatically.

In the preferred embodiment, each group control comprises a destination call control with immediate assignment. This has the advantage that each lift group can always choose the best lift of the group. Early recognition of the destination floor makes it possible to select from multiple lift cages that can reach the destination floor.

In a further embodiment, the group control of all lift groups is central multi-group control (MG
S). This has the advantage, among other things, that the selection from all the lifts in question can be made automatically from the central unit, when the ranges covered by several lift groups intersect.

In another embodiment, several routes can be used to reach the destination floor from the departure floor, where the most preferred route is determined. This has the advantage of solving the problems that arise with lift groups, i.e. the problem of some possible routes with changeovers. In this way, the optimum and fastest route from the departure floor to the destination floor is selected.

All of the features described are not only usable in the combinations indicated, but may be used in other combinations or on their own without departing from the scope of the invention.

[0012] Different embodiments of the invention are shown schematically and explained in more detail in the following description.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION Passengers in the lobby or on any floor enter a destination floor at one of the multi-group terminals. The central multi-group control MGS compares the desired course to its own databank or course array and the desired destination floor is one route, also called a route,
Confirm if you can reach it only.

If there is only one possibility that the destination floor can be reached by one or several changeovers, there is no problem in selecting the route.

For example, journey 1: use one group of high-rise shuttles and then descend by another group of lifts after changeover, or journey 2: use one group of low-rise shuttles and changeover after another. If there are several routes, such as climbing with a group of lifts, then the route that seems to be the shortest in time to the destination is first selected based on statistics and immediate travel conditions. After the best route selection, the extension strokes are broken down into individual stretches, usually served by different lift groups.

If one of the partial movements can be handled by several lift groups, a multi-group control to determine which lift to use first (eg US Pat.
(Described in P0891291B1) functions. If there is only one lift group, this multi-group control will determine the best lift.

The first lift used is evaluated and communicated to the passengers on the terminal display.

Central multi-group control MGS on the move
Tracks the time of lift movement across the course in relation to arrival at the changeover floor. As soon as the approach time to the changeover floor is determined (there is no further stop), the evaluation of the next group's best lift for the second stroke begins.

As soon as the next best lift is selected, the passengers in the elevator car can be informed. The next lift used for each destination floor, which can only be reached by changeover, is displayed on the elevator information system or other display. At the same time, the voice announcement system is activated. Furthermore, this indication can be combined for several destination floors and / or connecting lifts.

Some advantages of this solution are:

The central multi-group control MGS selects the best route from the departure floor to the destination floor and divides the selected route into individual sub-strokes, ie lift groups that select only the best lift at the best time. To divide,
In particular, this is the exact remaining time left for the previously used lift, the time to get off the lift, the walkway between two consecutive lifts, the time for the immediate lift to reach the changeover floor. , And known multi-group controls to determine the best lift (eg,
Based on all other factors used in patent EP 0891291 B1).

The passenger is informed, optically and audibly, of the next connection at the earliest possible time.

Immediate assignment is performed, that is, immediately after the destination call input, the passenger is assigned an elevator car.

The passenger does not have to carry around a device for indicating the destination.

FIG. 1 shows, for example, four group control computers GR1-PC, GR2-PC, GR3-PC,
Four group control GRs equipped with GR4-PC

Central multi-group control M by C, GR4-PC
Central multi-group control M, commonly combined with GS
The GS has a data bank DB and a multi-group control computer MG-PC.

The flowcharts of FIGS. 2 to 5 will be described in more detail below. Here, the flowchart of this example shows up to the third stretch for the purpose of simplification.

The passenger inputs a new destination call from the departure floor S to the destination floor Z.

The central multi-group control MGS can compare the desired journey with its own databank DB for the journey array and reach the desired destination floor by one route or by multiple routes W1, ...・ Confirm whether you can reach with Wn.

(Case A): When there are a plurality of routes from the departure floor S to the destination floor Z, the first route W1 is divided into stretches W1T1, W1T2, ..., W1Tn. Here, n is an integer. Furthermore, route W
, ..., Wn are also W2T1, ..., W2T

1, W1T2, ..., W1Tn; W2T1, W2T
2, ..., W2Tn and WnT1, WnT2, ...
., WnTn lift operating costs are examined in the respective group controls GR1, GR2, ..., GRn. Each stretch W1T1, W1T2, ... W
Tn; W2T1, W2T2, ..., W2Tn and W
The lift operating costs of nT1, WnT2, ..., WnTn are compared in the multi-group control computer MG-PC of the central multi-group control MGS to determine the preferred route FW. The lift is assigned to the group control computer that controls the first stretch, and the cancellation of instructions is performed on the remaining group control computers that do not have the first stretch on the preferred root FW. Next, the movement of the first stretch S-U1 from the departure floor S to the first changeover floor U1 is executed. After that, as soon as it is determined that there is no stop on the way, the multi-group control computer MG-PC is notified that the next destination is the changeover floor U1. In a similar manner, lift assignments are made to the selected lift group, from the first changeover floor U1 to the destination floor U1.
U1-U2 up to 1-Z or up to the second changeover floor U2 is executed. When the destination floor Z is at the end point of the second stretch, the second stretch U1-Z is moved, and the passenger reaches the destination floor. Destination floor Z
If is not the end point of the second stretch, the second stretch U1-U2 is moved to reach the destination floor Z using the same procedure as before for further stretches. In this example, the procedure is shown up to the third stretch, but it is clear that the same procedure can be used for further stretches.

(Case B): When there is only one route W1 from the departure floor S to the destination floor Z and a changeover is necessary, this route W1 is stretched by W1T1,
..., W1Tn is divided, and lift allocation is performed from the departure floor S to the first changeover floor U1 by the same method as described above. As soon as the transfer of the first stretch is complete, the same procedure as in case A) is used for the remaining stretches from the changeover floor U1. If no changeover is required, the normal journey from the departure floor S to the destination floor Z is performed.
